CONSTITUTION:Normal line printer papers are piled in double and the line printer paper 11 is passed between ribbons 8 and 9 while the line printer paper 12 is laid on the back of the outer ribbon 9. Then, two papers are printed simultaneously with a dot printer head 3. A resin sheet 10 is passed between the line printer paper 11 and the ribbon 9 to prevent printing on the back of the line printer paper 11. |
